Concave Face
The all-around application bit face specifically for medium hard and homogenerous rock formations.
Good hole deviation control and good flushing capacity.
Convex Face
For high penetration rates in soft to medium-hard with low to medium air pressure. It is the most resistance to steel wash, any may reduce the load and wear on gauge buttons, but poor hole deviation control.
